To all whom it concern:

'a citizenof the United States, residing at the city of Stu -Louis,-State'of Missouri,

have invented certain new and useful In1- provements in ConcreteConstruction,. (Divisional Case M,) of which the following is aspecification.-

This application is adi'vision and continnation of my Patent .No. 992733granted 16, 1909, Serial No. 528,298.

This invention relates to certain new and useful improvements inconcrete construction', and pertains particularly to a con-. structionin whi.ch"concrete slabs andbeams are used for ceilings and floors.

-' It .is the object of this invention to -pro vide a structure ofconcrete building ele-. ments which cooperate and are interengaged toform a unitary and rigid structure, and

further to provide a structure in which the beams support theslabs in anovel manner to be hereinafter more fully described." 2

7 In the drawings: Figure 1 is a/V16W in plan view, illustrating line. 33 of-Figr 2 and Fig-4 is ja-sectio'n on the line.L-t of Fig. 2;

It is to be understood that the "slabs-and beams; hereinaiter referredto may be made at any desired place, but preferably away from thelocation where. the building .in

"which they are used is being constructed.

Each beam 1 is 'provided w'ith shoulders 2 and atenon -3, the latterbeing prefer ably shorter than theleng'th of'bea 'n v1 and terminateswithin a short distance of each' In the present invention thereisemployed a pair of'small slabs '5' a'nda. large slab 6- of a 'len 'thapproximately equal to-that of the com inedlengths of both: slabs 5, the

of the beams and the. large or long slab 6 seating on the shoulders 2onltheopposite sides of said --bea rns.' The slabsqare prefen ablymolded; or, formed with depending @flanges 7 on',..their under faceswhich latter directly to the. column.

seat on 'the'shoulders2, and act to obv p i f' strengthen the slabs; Theflanges 7 -raise the .top faces of the slabs-so that the same arelocatedlrabove-t-he. tops of the'tenonsfi so that, when a slab'is-placeduponeach f shoulder 2 of a beam,-"aspacej8 is left above? tenon 3 andbetween the'twoslabs supported .60 ,with the top faces of the slabs,which grout 4 or wet concrete becomes-set in said space .between'theslabs and the beams andr'there -ga by unites said partsand constitutes amono; lithic structure. 4 The'fflangesfl may be oinit ted, and the slabst5 and 6 formedofsuchthickness that the top faces thereof will be raisedto; a higher elevation ,thanthefitop of? tenon 3; when the slabedges-are placed; on shoulders 2, ina manner above described;

A gusset'9, or a pluralityofsuchgussets are formed on column 10,-; thegussets being provided with cutaway portions 11 oII';= t-heirupper-endswhich communicatewith a slot 12formed in the inner end-of each bea'm"1.

The inner ends of. the beams abut asseenf 1n.Fig.-2,'and the slots12-registr withleach other.

Relnforcing bars 16 areembedded in the upper parts of tenons 3, and protrude fromthe tenonends, being located preferably above reinforcing bar. 14;; The bars 15md ;16 are. preferably of suflicient length to overlap the similarbarsl5 and 16 projectv ing from the tenon of a beam extending In thesamedirection, as shown in Figs. 1

and 2.

The shoulders 2 are provided with reinforcing bars 17 which areencircled at intervals by bars'l8j U-shaped reinforcing bars 19 arespaced at intervals in the beams 1, and the lower part of eachobar 19preferably underlies bars 15. The ends of each bar 19 extend-within ashort distance of the top of tenon3, as depicted in Figs. 1, 3, and 4:,or said ends can project above the tenons 3 into space 8. Reinforcingbars 20. are em- -bedded in each of the slabs 5 and 6, and

those-rods which extend at an angle to space 8 preferably project intosaid space.

. In Fig. 2, the dotted lines indicating reinpresent invention, thecolumn 10 is erected,

and the beams placed thereon in abutting relation so that their slots 12register and -bar 14 projects into said registering slots 12.

The slabs 5, 5, and 6 are then positioned on the shoulders-2 of the twobeams so that their flanges 4 abut tenons 3. The outer ends of the beamsare supported by uprights "or any other suitable means ofsupport, notshown; The sides of the cutaway portions 11 are then covered with socalled forms, 45

not shown, whereupon grout or" wet concrete is poured into slots 12 andthe spaces 8 When the grout or wet concrete has become set, a, unitarystructure comprising the above mentioned elementsis obtained,

and the juncture of the elementsis greatly strengthened by virtue oftherelnforcing bars.
